Detailed Description:
-
Core Function: Serves as the power section of the drive system, converting DC link voltage into AC voltage with variable frequency and amplitude to precisely control motor speed, torque, and position.
-
Modular & Compact Design: Features a standard booksize design with a width of 50 mm, enabling side-by-side high-density mounting to maximize control cabinet space utilization. Quick commissioning, module identification, and communication are facilitated via the integrated Drive-CLiQ interface.
-
High-Performance Control: Supports servo control and vector control, enabling high-precision closed-loop control. The module integrates a braking chopper, allowing direct connection of an external braking resistor to safely dissipate regenerative energy generated during motor braking or deceleration.
-
Safety Integration: Supports Safety Integrated (SI) extended safety functions (requires a compatible control unit and license), enabling safety features such as Safe Torque Off (STO) and Safe Stop (SS1/SS2) to meet relevant safety standards.
-
Communication & Diagnostics: Seamlessly integrates into the SINAMICS S120 system via the Drive-CLiQ interface and can support fieldbus communications like PROFIBUS and PROFINET through the superior control unit. It offers comprehensive status monitoring and fault diagnostics.
-
Typical Applications: Widely used in applications requiring high-performance single-axis drives, such as spindle drives, feed axis drives, winding equipment, and various high-precision positioning systems.
